Bushed Chain Coupling Sprocket Size Chart
When it comes to efficient power transmission in confined spaces, bushed chain coupling sprockets are an essential solution. Designed to ANSI standards but engineered with a smaller outside diameter and a special tooth profile, these sprockets ensure smooth, reliable operation inside a coupling cover — maximizing performance and minimizing wear.
See coupling sprocket tooth profile below.
How Bushed Chain Coupling Sprockets Work and Common Applications
Chain coupling sprockets work by connecting two shafts together using a roller chain. Each shaft is fitted with a sprocket, and the chain wraps around both sprockets, transmitting torque while allowing for slight misalignment between the shafts. The special tooth profile is designed specifically to seat the chain securely and run efficiently within the coupling cover, reducing vibration and promoting longer system life.
These components are commonly used in applications such as conveyors, mixers, pumps, and various types of industrial machinery where space is limited, and where robust, easy-to-maintain connections are required.
At MDS of Michigan, we offer a wide selection of chain coupling sprockets available in two popular bushed styles: QD Bushed and Taper-Lock Bushed designs. Each sprocket half is crafted from high-quality, heat-treated steel to ensure superior performance, high torque capacity, and long service life.
Choosing a bushed roller chain coupling sprocket offers greater flexibility, easier installation, and stronger shaft grip compared to a plain or finished bore sprocket. Bushed designs allow for quick changes in shaft size, better torque transmission, and reduced shaft wear through even clamping pressure. This makes them ideal for demanding applications where long service life and simplified maintenance are critical.
